妙法蓮華經玄義 10.66

10.66

不定觀者，從過去佛深種善根，今修證十二門，豁然開悟，得無生忍，即是毒在乳中，即能殺人也。若坐證不淨觀，九想、十想、背捨、勝處、有作四聖諦觀等，因此禪定，豁然心開意解，得無生忍，即是毒至酪中殺人也。若有人發四私誓願，修於六度，體假入空，無生四諦觀，豁然悟解，得無生忍，即是毒至生蘇殺人也。若人修行六度，修從空出假，修無量四諦觀，豁然心悟，得無生忍，是毒至熟蘇而殺人也。若有坐禪，修中道自性等禪正觀，學無作四聖諦，行法華、般舟等四種三昧，豁然心悟，得無生忍，即是醍醐行中殺人也。

As for the indeterminate contemplation: having deeply planted good roots under past buddhas, now cultivating and realizing the twelve gates, one suddenly awakens and attains the endurance of non-arising: this is poison placed in milk that can kill people. If, through realizing the contemplation of impurity in meditation—the nine notions, the ten notions, the [eight] liberations, the [eight] masteries, the contemplation of the four noble truths of active creation, and so forth—one suddenly opens one's mind and understands, attaining the endurance of non-arising due to this dhyāna concentration: this is poison reaching coagulated milk to kill people. If someone generates the four vows, cultivates the six perfections, identifies provisionality to enter emptiness, and in the contemplation of the four truths of non-arising suddenly awakens and understands, attaining the endurance of non-arising: this is poison reaching curd to kill people. If someone cultivates the six perfections, cultivates emergence from emptiness into provisionality, and cultivates the contemplation of the immeasurable four truths, suddenly awakening in mind and attaining the endurance of non-arising: this is poison reaching refined butter to kill people. If someone sits in meditation, cultivates the correct contemplation of the Middle Way, the dhyāna of self-nature, and so forth, studies the uncreated four noble truths, and practices the four kinds of samādhi such as the Lotus and Pratyutpanna, suddenly awakening in mind and attaining the endurance of non-arising: this is killing people within the practice of ghee.
